Hey all! As the title says, previous owner had my car tuned by someone that locked the tune. Have no contact with him and have zero idea of who did the tune.

Texas Speed and Performance LQ9 408ci 6.6L GM Gen IV Iron 6.0L LQ9 Block
ARP Main Stud Kit
TSP 4.000? Forged Crankshaft

It runs and drives decent. It just doesn't run great. Seems like something is off, but I cant tell because the tune is locked. Also, I want to get all the Christmas tree lights off the dash and get it tuned to where it runs better.

If the previous owner locked the tune on your 2001 Pontiac Firebird Trans Am, you’ll need to start fresh with a new base tune. Since you already have an HPTuner MPVI3 with 2 credits, you can use this device to read the current ECU configuration. First, ensure you have the latest software and drivers for your MPVI3. Connect the MPVI3 to your car’s OBD-II port and to your laptop. Open the HPTuner software, and follow the steps to read the existing tune. Save this file for reference.

Next, acquire a base tune file compatible with your vehicle and modifications. You may find base tunes online, or you can contact a reputable tuner who can provide one. Once you have the base tune, use the HPTuner software to flash it to your car’s ECU. Ensure all settings align with your specific modifications to avoid potential issues. This process will overwrite the locked tune, giving you a fresh starting point for any further tuning adjustments.

Hey @G Atsma , what's the sniff test here? Real user or bot? If this is a bot, AI is getting real good with the advice, lol

Welcome! Beautiful TA you have! If you are not familiar with tuning I would take it to a reputable tuner. I have a very similar build but I am running the aluminum 6.0 with the TSP 408 and a built A4 with a 3200 stall.

To get a base tune for your 2001 Pontiac Firebird Trans Am with extensive mods, you'll need to start by purchasing a base tune file from a reputable tuning company that specializes in your vehicle. Using your HPTuner MPVI3, you can then flash this base tune over the old one. It's crucial to provide the tuner with your complete mod list for the most accurate base tune. Additionally, you may need to buy more credits depending on the tuner and the specific requirements of your vehicle. If you're not experienced in tuning, consider consulting a professional to avoid any potential issues.

Defiantly looks like some AI response. And now the AI is dumb enough to reply twice.
